when the sleeve 28 is moved axially by handwheel 55 to permit suchengagement. The clutch 3| is integral with a gear 32 freely mounted forrotation on the sleeve 24 and has a shoulder 33 abutting the shoulder 34of sleeve 24 and a corresponding shoulder formed by the collar 34' onthe opposite side secured to sleeve 24. The teeth of gear 32 mesh with agear 35 keyed to the shaft 36 rotatably mounted at its opposite ends inthe bearings 31 and 38 in the frame 8. Gear 35, which forms no essentialpart of the present inventions is merely illustrated as it happens to bepart of the completed machine and transfers power for other operationsof the mechanism.

Power from a source (not shown) drives gear 32,

which, when the clutch jaws 3| and 30 are in engagement, produces acorresponding rotation of the sleeve 28. Sleeve 28 keyed to the sleeve24 in turn drives this sleeve, and sleeve 24 through its connection tosleeve l5 by way of the screw |1 drives the latter, which in turn isconnected through a key It to the shaft extension |2, thereby drivingthe drum I.

The angular adjustment of the drum l'wi th respect to drum 2, inaccordance with my invention by means of the driving connection betweenthe sleeves 24 and I5 illustrated in detail in Figure- 2. The screw |1meshes with internal teeth 42 of a gear. Gear 43 which is securely heldagainst axial movement between lugs 44 and 45, which form an integralpart of sleeve I5, is provided with external teeth which mesh with theteeth 48 of the rack 41 iFigure 1). Screw I1 is provided with a keyway5| (Figure 2) which engages a key 5| extending from sleeve |5 to prevent"rotation of the screw l1.

As the rack 41 is moved axially in a manner to be described hereinafter,the gear 43 is rotated. Inasmuch, however, as the screw I1 is restrainedfrom rotation, and gear 43 is prevented from any axial movement by thelugs 44 and between which it is held, the only possible movement is anaxial movement of screw H with respect to gear 43. The head of screw Hin contact with block l8 thus produces a tangential force on sleeve |5as a result of which a rotation of sleeve I5 is produced together with arotary movement of the entire connection including the screw l1, gear43, and lugs 44 and 45 as illustrated in Figure 3 by the new positionwhich these parts have taken up. Since the rotation of sleeve l5produces therewith a corresponding rotation of the drum I through thedriving connections described in detail above, this angular adjustmentof the sleeve |5 with respect to sleeve 24 produces a correspondingadjustment of the drum I.

Referring now again to Figure 1, the method of rotating the rack 41 forproducing this adjustment will now be described. Rack 41, freely mountedfor axial slidable movement in sleeve 5 but engaged for angular movementthrough keyway 41 in rack 41 and key l5 secured in sleeve l5 which inturn is slidable on the shaft 55, has one end thereof hollowed as at 58and has at this end an internal threaded portion 51 which engages thethreads of a block 58 rotatable on screw 53 through the bearing 1|. Theteeth 58 of screw 59mesh with the internal teeth of worm gear 5|. Theouter teeth 82 of worm gear 5| in turn mesh with the worm 83 which iskeyed to shaft 65. One end of shaft 55 is secured to the handwheel 56(Figure 4). As the handwheel 86 is rotated, shaft through the worm 63rotates the worm gear 6|. Inasmuch as the worm gear 8| in turn is fixedagainst axial movement between the block 81 at one end thereof fixedworm 68.

and the worm 88' at the other end thereof, and the screw 58 in turn isrestrained from rotation by. the slot or keyway 81' and cooperating keyblock 81 as shown in Figure 4 rotation of worm. gear 6| will cause anaxial movement of the screw member 58, causing a corresponding axialmovement of the rack 41. Rack 41 in turn draws gear 43 for producingfine adjustments of the drum I as has already been described. Althoughrack 41 rotates with sleeves l5 and 24, in the manner that will now beobvious, about screw 59 on bearings 1|, this entire mechanism can beshifted axially and it will be obvious that adjustments may therefore beobtain d while the apparatus is in operation. a

In order to obtain longitudinal adjustments of the cylinder I, the shaftextension- 2 is mounted for rotation about bearings 12 mounted in turnon shaft 55. Shaft 55, which is free to rotate in bearings 12 at one endand is keyed to the screw 58 forming the sleeve thereof at its otherend, is provided with a screw member 13 at its free end which mesheswith teeth in the The teeth 14 of worm 88 mesh with the worm 15. pinnedto the shaft 16 for rotation therewith. Shaft 18 in turn is connected tothe handwheel 11 for rotation thereby. As the handwheel 11 rotates todrive shaft 16, the worm 15 rotates worm gear 68. Worm gears GI and 88are mounted in a housing 18, which consists of the upper member 19 andlower support member 80 arranged so as to form bearings for the wormgears 6| and 68 and their corresponding worms and handwheels. The entireunit is mounted to main frame 6 by means of an extending brace 8|.Inasmuch as the worm gear 68 is fixed against axial movement in thehousing 18 which also houses the worm gear 8|, as the worm gear 68rotates, and inasmuch as screw 13 is locked against rotation by reasonof the engagement of the keyway in screw 59 by the key 64 of shaft 55 anaxial movement of the screw 13 is produced producing a correspondingmovement of shaft 55. As the shaft 55 is moved axially it carries withit its bearings 12 and the housing 18 to move shaft extension l2 anddrum longitudinally for displacement with respect to drum 2. Shaft |2 byreason of the key 5 which engages keyway I8 is adjustable longitudinallywith respect to the sleeve l5.

The operation of my mechanism will now be obvious. Normally, forproducing rough adjustments of the drum I, I disengage clutches 30 and3| by the handwheel 28 which carries the sleeve 28 to the right. Withthe clutches 30 and 3| disengaged handwheel 28 may be rotated to in turnrotate the drum until an approximate adjustment has been obtained. Afterthe rough adjustment has been accomplished, the handwheel 29 is operatedto move sleeve 28 to the left until the clutch jaws 30 and 3| engage.Thereafter, with the apparatus in operation, by observing printingoperations, adjustments may be made first with the handwheel 65.Operation of the handwheel 68, as explained above, results in alongitudinal movement of the rack 41 which, in turn, produces a rotatingmovement of gear 43. The rotation of the gear 43, because of thenon-rotating condition of worm l1 and because of the restraining of gear43 between the lugs 44 and 45, can be translated only into a rotation ofthe connection between sleeves 24 and IS with respect to sleeve 24.Similarly to produce axial movement of the drum, the handwheel 11 isoperated, which operates through the shaft 55 to move the shaft l2 anddrum. l axially required amount.
